DETACHABLE ROLLER-SCREEN.

Specification of Letters Patent.

Patented July 4, 1916.

Application filed October 21, 1914. Serial No. 867,850.

To all whom it may concern:

Be it known that we, GEORGE MAIN and Jesse M. STANSELL, citizens of the United States, residing at Centralia, in the county of Marion, State of Illinois, have invented certain new and useful Improvements in Detachable Roller-Screens; and we do hereby declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled'in the art to which it appertains to "make and use the same.

The invention relates to a detachable roller screen.

An object of the invention is to make provision for the screen of a window in such manner that the screen used will be located entirely within the upper and lower casings of the window frame when not in use.

' A further object of the invention is to so construct the device that the screen may be detachably secured to the upper and lower sashes so that as the said sashes will be raised or lowered the screen will be operated to cover the open spaces.

A further object of the invention is to so construct the device that immediately upon the detaching of the screen from the sashes they will be drawn within the aforementioned casings. 7

With these and other objects in View, such as will appear as the description progresses, our invention comprises the combination and arrangement of parts as herein 'set forth and falling within the scope of-the appended claim.

, Referring to the drawing :Figure 1 is a front elevation of a,frame with our device in place therein, parts of the frame being broken away to more clearly disclose the device. Fig.2 is a longitudinal sectional View thereof. Fig. 3 is a fragmental view showing the manner of detachably securing the screen to the window sash. Fig. 4'is a fragmental vlew of one of the rollers, the screen being attached thereto. Fig. 5 is a detail of the anti-friction bearing employed. Fig. 6 is a section on line 66 of Fig. 1.

Referring to the drawing-wherein like parts are indicated by like characters throughout the several views :The frame which is indicated generally by the reference character 1 has the ordinary upper and lower casings 2 and 3. The face of the lower casing 3 is cutaway, as at 4, so as to allow the insertion and mounting of the Secured within this casing 3 are vertically mounted a metallic spring roller 8, the inner core 9 of which is rigidly held in the bearing 6, while the projection 10, is formed integral with the outer casing 11 of the said roller and extends through a collar 12 of the bearing 7, which collar is rotatably mounted on ball-bearings 13 in a cup 14, the said cup being fixedly secured in the brackets 15.

Extending longitudinally of the roller 8 is a slot 16 in which is detachably secured a strip 17 by means of a flange 18, which flange extends intothe said slot. Secured to this strip 17 by' means of a flange 19 is a strip of screen 20 which is of a width equal to the Width of the window sash. This strip extending bearings 6 and 7 in which is 8 and through a slot 21 in the lower sill 22 immediately in front of the window stool 23. Onthe upper end of'this screen 20 is a strip 24 similar to the strip 17 and having a flange 25 thereon, which flange is adapted to be detachably engaged with a flange 26 on the lower end of the lower sash. Normally when the said strip 24 is disengaged from the flange 26 on the said sash the spring actuated roller 8 operates to wind the screen 20 about itself until the strip 24 lies within the slot 21 in such manner that it will be completely hidden from View. This same operation takes place when the sash is lowered even while the strip 24 is secured thereto. In order that thescreen may be drawn upwardly against the tension of the roller 8 .so as tobe attached to the sash, we have provided on the strip 24 a handle 27 which extends out of the slot 21., When the screen is secured to the lower sash, this handle lies in a cut-out portion 28 in the lower art of the said sash so as to present no projecting parts. It may be thus seen that after the screen has been at-' said roller and screen being similar to those preyiously described. In order that access may be had to this roller and screen, we have provided a detachable plate 31 which forms the forward face of the said casing 2. This screen passes through the slot 31 in the head block 32 immediately behind the stop for the upper sash and is detachably secured to the upper end of said sash in a manner similar to that in which the lower screen is attached to the lower sash.

It will be readily appreciated that the form of window frame that we have described is of the ordinary construction with the exception of the cut-away portion in the lower casing and for this reason the screen may be readily applied to old frames without materially altering the construction thereof which will make the application of these screens very easy and exceedingly inexpensive.

It may be thus seen that either or both of the sashes may be-raised or lowered at will, and yet the spaces caused by the opening thereof will be efiectively covered by the screens. c It will i be further seen that when the screens are not in use they will be contained entirely in the casings and thusefi'ectively protected from the weather.

It will be further seen that by providing the particular form of rollers and bearings that the operation of the screen will be insaseo greatly facilitated, and when the said screens are detached from the sashes they will be returned immediately to their positions within the casings.

While we have described and illustrated a particular embodiment of our invention, we wish it to be understood that we do not wish to be limited to that particular embodiment for it is obvious that numerous changes may be made within the scope of the invention as defined by the claim.

What is claimed is In combination with a window frame, a plurality of bearings mounted in the lowermost casing thereof, one of said bearings comprising upwardly extending brackets, a

ball-bearing cup secured thereto, ball-bearings in said cup, a sleeve extending through said cup and rotatably mounted on said bearings which have outwardly extending projections thereon, one of said projections being rigidly securedto one of said bearings, and the other of said projections extending through said sleeve and rotatable therewith.

In testimony whereof, we afix our signatures, in the presence of two witnesses GEQRGE MAIN.
